So they don't deserve to deal with it, but you agree they should deal with it anyway, as long as the idea is good?

No. F that. How can you discourage inappropriate behavior and then, in the very same thought, find a way to excuse it?

On a basic level I don't agree with listening to insanity because it encourages it. There shouldn't be a point where you're like "well, on one hand this person threatened to kill the developers family, but on the other hand transmog would be pretty sweet."

Beyond that, what constitutes a good idea? A lot of these games don't implement bad practices because they didn't have INMATEofARKHAM to inform them that grinding for 10 million hours isn't appealing. They almost certainly know what sucks, what people would like to see, and all of that. They just don't do it because it negatively impacts things. Case in point, Bungie killed the grind with Destiny 2 vanilla and I've never once seen someone say they miss that time. They might make suggestions that brings us back to it, but no one is like "you know what would be sweet? Static rolls and guaranteed drops."
